very truthfully speaking, i doubt i would do either one of those things (get mad or cry) because i do not think that the movies were that great compared to the books and also because it was one of those 'happily ever after' endings. Those types of endings don't really send me to the ground crying or make me burst out in anger.
However, i may be surprised.. we will just have to wait and see, won't we?
Well its the end of the saga we all know and love, so yeah, who wouldnt be upset? But I we could always imagen the stories going on, and we still have the books and cds and Dvds to hold on and watch for generations more. We can pass them on to are freaken kids if we wanted to! There not going anywere! And I bet alot of fans will take over the series and there own extensions. Pfft I already have. So even though Breaking Dawn is the last one, its not the end of the series, The saga will live on! No need to cry or get mad..
